UNSPSC 40173711: Copper pipe reducing flange

Reducing flange made of copper

UNSPSC 40173711 Copper pipe reducing flange is a Commodity code for a specialized plumbing component, though recent state and local solicitations tagged with this code show minimal activity directly procuring the product itself. Instead, the code appears in the context of broader sewer infrastructure rehabilitation and pavement projects where such fittings may be incidental materials within larger scopes. State and local governments use this code when purchasing or specifying copper reducing flanges as part of water, wastewater, and stormwater system construction and repair work. The issuing bodies are primarily special-purpose districts and county departments responsible for utility infrastructure — in the recent record, Santa Clara County's sanitation district and the County itself.

Santa Clara County dominates the recent activity under this code. Two ITB solicitations posted in 2026 show the geographic concentration: the County Sanitation District No. 2–3 Structural Defect Repair Project Phase 2 (ITB ITBRDAFY270088, due September 17, 2026) for sewer mainline point repairs, pipe-burst replacements, and extensions in the unincorporated eastern foothills, and the Central Expressway Pavement Rehabilitation Project Between Bowers Avenue and Scott Boulevard (ITB ITBRDAFY260694, due May 21, 2026) for comprehensive pavement and drainage improvements. The sanitation district project emphasizes removal and replacement of vitrified clay and cast-iron pipes with PVC and HDPE, along with service connection fittings and precast concrete structures. Neither solicitation explicitly highlights copper reducing flanges as a line item, suggesting that when they are specified, they are minor components within projects dominated by larger-diameter mainline pipe, concrete work, and asphalt overlay. Activity under this code remains limited and geographically narrow.
